pamtohtmltbl [-transparent=color] [-verbose] [file]
Minimum unique abbreviation of option is acceptable. You may use double hyphens instead of single hyphen to denote options. You may use white space in place of the equals sign to separate an option name from its value.
This program is part of Netpbm(1).
pamtohtmltbl converts a visual image to an HTML table with one cell per pixel. The cell is empty, but its background color is that of the pixel.
file is a PBM, PGM, PPM, or PAM file. If PAM, it must be a standard visual image of tuple type RGB, GRAYSCALE, or BLACKANDWHITE, or something equivalent with extra higher numbered channels, but pamtohtmltbl doesn't check the tuple type; it just assumes.
Note that the more normal way to include a visual image in an HTML document is with a <IMG> tag.
Not all web browsers render tables as pamtohtmltbl expects, and therefore show a grossly distorted image. Internet Explorer 7 on Windows and Opera 9.02 on Windows have been seen to work; Firefox 188.8.131.52 on the same Windows system has been seen not to.
In addition to the options common to all programs based on libnetpbm (most notably -quiet, see Common Options ), pamtohtmltbl recognizes the following command line options:
This option indicates that pixels of the specified color are to be transparent in the HTML table. The table cell for a pixel of this color will have no background color specified.
Specify the color (color) as described for the argument of the pnm_parsecolor() library routine .
This option causes pamtohtmltbl to display messages about the conversion process.
pamtohtmltbl was new in Netpbm 10.15 (April 2003).
Alexander B. Ivanov (SSH) wrote a program he called pnm2html. Bryan Henderson adapted it to use the Netpbm libraries and handle PAM images and follow Netpbm conventions, and named it pamtohtmltbl.
